Sora Narukami, younger sister of Yota Narukami and daughter of Daichi and Tokiko Narukami, sports waist-length red hair tied in a ponytail, with shorter strands framing her face, complemented by striking pink eyes. Her attire often includes an off-white dress shirt, a pink tie, a navy blue skirt, matching socks, and pink shoes.

An active member of her school’s film club, she spends her summer crafting a movie for a homework assignment, a project subtly intertwined with the central storyline. Initially aloof toward the eccentric Hina Sato, Sora reluctantly finds herself entangled in unforeseen events after aiding Hikari Jinguji in evading debt collectors—an act that leaves her injured, sparking her family’s worry and prompting Hina and Yota’s involvement in Hikari’s plight.

Her film evolves into a narrative cornerstone, concluding with a scene where she screens the finished work alongside Hina and Yota, blurring the lines between her fictional creation and their real-life trials. Personality-wise, she embodies teenage pragmatism: indifferent to pursuits outside her interests yet stubbornly loyal to those she cares about. Her name—"Sora" (sky) paired with "Narukami" (to "become god")—hints at latent symbolism contrasting her understated presence.

Though her arc remains secondary, her journey reflects gradual growth, shifting from wary skepticism of Hina to quiet participation in larger conflicts. This progression underscores her role as an anchor to reality amidst supernatural undertones, with development conveyed through steadfast dedication to her film and familial connections rather than overt transformation.
